Figure 2. Examples of metal pieces obtained by laser milling
The case study is described by an initial data set of 35 samples with 7 input variables (Number of pieces, Radius,
Type of tool, Revolutions, Feed rate X, Y and Z) and 2 output variables (Erosion and Real time of work) as showed
in “TABLE I”. Time errors for manufacturing are the difference between the estimated time by the machine itself
and production real time.
